Cooking assembly that saves energy, reduces noise, and circularly removes fumes

ABSTRACT

A cooking assembly that saves energy, reduces noise, and circularly removes fumes comprises a venting outlet disposed opposite to an absorbing inlet of an absorbing device. The air expelled from the venting outlet permits guiding fumes and smells generated during cooking into an absorbing scope of the absorbing inlet, thereby offering a recurring air curtain over a cooking platen. The cooking assembly keeps heating energy but takes away the cooking fumes and smells from the cooking platen via a consistent and recurring operation to clarify the air. The recurring air curtain avoids wasting air conditioning energy and prevents from leaking the air polluted by fumes out, which allows the cooking assembly to omit an extra outdoor discharging pipe but attain a fresh and tranquil dining atmosphere, and decrease the energy consumption of the facility for being friendly to the environment.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a cooking assembly, particularly to ateppanyaki platform of the cooking assembly that saves energy, reducesnoise, and circularly removes fumes.

2. Description of the Related Art

Referring to FIG. 1, a conventional cooking assembly 1 comprises aplatform 11 provided with a cooking platen 12 and a filter 14 installedin the platform 11 for drawing cooking fumes on the cooking platen 12.Wherein, the platform 11 has an air unit indisposed thereon. The filter14 includes an absorbing inlet 141 defined on the air unit 111, aventing outlet 142 defined on one side of the platform 11, a filteringunit 143 installed in the platform 11, an air pump 145 disposed on theplatform 11, and an air channel 144 connected with the absorbing inlet141, the venting outlet 142, the filtering unit 143, and the air pump145. The cooking fumes generated curing frying on the cooking platen 12are drawn by the absorbing inlet 141 via the operation of the air pump145 and filtered by the filtering unit 143 so as to be expelled via theventing outlet 142. Whereby, the cooking fumes do not disperse away fromthe cooking platen 12, and consumers can enjoy their fine food in asmokeless environment.

However, the conventional cooking assembly 1 has the followingshortcomings:

1. The cooking assembly 1 is usually operated in an air-conditionedspace. Wherein, when the cooking fumes are drawn and filtered, thecooled air is also sucked. Accordingly, in order to keep a moderatetemperature in the dining space, the operating power of the airconditioner must be sufficient to cool the dining space. However,increasing the operating power of the air conditioner concurrentlyaugments the expense of electricity.

2. The absorbing inlet 141, which is near the cook, is fixed on one sideof the cooking platen 12. Herein, a convection of air is easily occurredand speeded up when the cooled air from the air-conditioner meets theheating air on the cooking platen 12. Whereby, the cooking fumes on thecooking platen 12 adversely scatter in view of the convection, and thefixed absorbing inlet 141 can not directly absorb the cooking fumes, sothat the dinning environment becomes smoky.

3. Further, in order to efficiently expel the cooking fumes from thecooking platen 12, the air pump 145 must operate with sufficient poweror rotation speed to increase the absorbing power. However, theabsorbing efficiency of the air pump 145 is still limited since thecooking fumes scatter in an open space. Moreover, the higher therotation speed of the air pump 145 is provided, the more noise isgenerated.

4. When the operating efficiency of the air pump 145 is enhanced, morecooled air from the air-conditioner is concurrently absorbed, and so isthe thermal heat on the cooking platen 12. Therefore, besides wastingthe air-conditioner energy, the heating energy such as fuel gas is alsowasted.

5. The filtering unit 143 may be able to clean the cooking fumes.However, since the components of the cooking fumes are different, it isdifficult to completely eliminate the smelly odor of the cooking fumesunless the filtering unit 143 provides manifold purification.Nonetheless, the conventional cooking assembly 1 simply absorbs cookingfumes and expels it right away, so there is in fact insufficient time topurify the reek of the cooking fumes. Accordingly, when different foodsare cooked on respective cooking platens 12 of the cooking assemblies 1,the reek of the cooking fumes is mixed in the air and influencesconsumers, which ruins the dining atmosphere.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Wherever possible, the same reference numbers are used in the drawingsand the description to refer to the same or like parts.

Referring to FIG. 2, a first preferred embodiment of the presentinvention is shown. A cooking assembly 3 that saves energy, reducesnoise, and circularly removes fumes comprises a platform 31, a cookingplaten 32 disposed on the platform 31 for cooking, and an absorbingdevice 33 installed in the platform 31 for absorbing cooking fumes onthe cooking platen 32. The absorbing device 33 has at least oneabsorbing inlet 331 disposed near the cooking platen 32 for absorbingthe cooking fumes on the cooking platen 32, a first air channel 334connected to the absorbing inlet 331 for guiding the fumes, and an airpump 333 connected to the first air channel 334. Wherein, at least oneventing outlet 332 is disposed on the platform 31, opposite to theabsorbing inlet 331. In this embodiment, a second air channel 36 isconnected with the venting outlet 332, and an end of the second airchannel 36 is connected with a blower 361 for causing a current of air.Moreover, the absorbing inlet 331 and the venting outlet 332 can bedefined on the platform 31. Alternatively, the platform 31 can beprovided with a first air unit 311 as well as a second air unit 312,corresponding to the first air unit 311, so that the absorbing inlet 331is defined on the first air unit 311 and the venting outlet 332 isdefined on the second air unit 312, respectively. In this embodiment,the first air unit 311 and the second air unit 312 is provided.

Referring to FIGS. 2 and 3, in operation, the blower 361 gives externalair to the absorbing inlet 331 via the venting outlet 332. Whereby, theair pump 333 is able to draw the air within an absorbing scope of theabsorbing inlet 331. Herein, the blower 361 giving external air and theair pump 333 drawing the air conduce to a recurring air curtain to beformed on the cooking platen 32. Wherein, the recurring air curtainassists the absorbing inlet 331 in capturing cooking fumes. Namely, thecooking fumes surrounding consumers will be guided into the absorbingscope of the absorbing inlet 331 by the air from the venting outlet 332.After that, the cooking fumes sucked via the absorbing inlet 331 will beexpelled via the first air channel 334. Preferably, a dinning space iskept fresh since the cooking fumes and smells do not scatter; namely,the cooking fumes are meticulously collected and smelly odors areprevented. The present invention is prevented from promoting theoperating efficiency of the air pump 333 and installing an outdoordischarging pipe. Further, since the absorbing inlet 331 simply drawsthe cooking fumes on the cooking platen 32 and the air given from theventing outlet 332, cool air in the dinning space is prevented fromwasting. Concurrently, a complementary cooperation of the blower and theair pump keeps the heat energy for cooking on the cooking platen 32.Unlike the present invention, the conventional cooking assembly merelyprovides a single absorbing inlet with powerful suction to suck thecooking fumes, which adversely draws the heat energy near the absorbinginlet on the cooking platen at the same time. Accordingly, when thepresent invention prevents the heat energy from running off, the heatenergy such as gas will not be over-consumed and a stable heating isguaranteed.

FIG. 4 shows a second preferred embodiment of the present invention. Thecooking assembly 3 similarly comprises a platform 31, a cooking platen32, and an absorbing device 33. Characterized in that, the first airchannel 334 is further connected with a filter 34 for removing smoke,and a purifying device 37 for purifying smells. Further, one end of thefirst air channel 334 is connected with the venting outlet 332.Referring to FIG. 5, in operation, the air pump 333 is operated tocooperate with the absorbing inlet 331 for drawing the cooking fumes andsmelly odors generated on the cooking platen 32. Thence, the filter 34and the purifying device 37 cooperatively remove the smelly molecules inthe cooking fumes so as to purify the air accordingly. Afterward, thefiltered cooking fumes and the purified air result in cleaned air thatis given out from the venting outlet 332 toward the absorbing inlet 331.Thus, besides the air recurring function similar to that of the firstpreferred embodiment, the temperature of the discharged cleaned air issomewhat maintained on the cooking platen 32 since the recurringfunction keeps the cleaned air traveling over the cooking platen 32.Accordingly, the heat energy on the cooking platen 32 does not scattereasily. Moreover, by means of the recurring function, the air in thedinning space is continuously purified by the purifying device 37, whichefficiently removes the smelly odors existing in the air. Additionally,when the recurring function keeps the cleaned air traveling over thecooking platen 32, cooking smells generated while frying foods can bereserved on the respective cooking assemblies 3. Namely, the smellyodors do not scatter and mix in the air in the dinning space, whichensures the consumer of a fresh dinning space.

FIG. 6 shows a third preferred embodiment of the present invention. Thecooking assembly 3 similarly comprises a platform 31, a cooking platen32, and an absorbing device 33. The like functions and structurescorrelated to that of afore preferred embodiments are herein omitted.Differently, a connecting wall 35 is disposed between the platform 31and the cooking platen 32. Wherein, the connecting wall 35 is disposedslightly higher than the cooking platen 32, so that the venting outlet332 can be defined on the connecting wall 35. In fact, the absorbinginlet 331 can be concurrently defined on the connecting wall 35,opposite to the venting outlet 332, as shown in FIG. 7. Herein, when theabsorbing inlet 331 and the venting outlet 332 are defined on theconnecting wall 35, an invisible structure is provided, whichfacilitates the operation of the cook or the consumer.

To sum up, the present invention particularly devotes thecorrespondently disposed absorbing inlet and venting outlet to pushingdischarged air from the venting outlet to the absorbing scope of theabsorbing inlet. Namely, cooking fumes generated on the cooking platenis motivated by the discharged air from the venting outlet toward theabsorbing scope of the absorbing inlet, so that the cooking fumes can becollected more thoroughly. Accordingly, the cooking fumes on the cookingplaten do not scatter easily, the air conditioner in the dinning spacedoes not waste electricity too much, the operation efficiency of the airpump does not have to be enhanced, the dinning atmosphere is more freshand tranquil, and the environment is protected.
